Survey 2025: Repository data of EPFL - École Polytechnique Fédérale de Lausanne (2021-2024)

EPFL has processed data on scholarly publications published between 2021 and 2024 and written by affiliated researchers. The bibliographic data were taken from EPFL’s institutional repository, Infoscience (https://infoscience.epfl.ch/), and enriched with metadata from OpenAlex (https://openalex.org/) to classify publications into four models (gold, hybrid, green and closed) in response to the Swiss Open Access Monitor’s annual survey (Repository Monitor – https://oamonitor.ch/charts-data/repository-monitor/). The datasets comprise four publication types (journal articles, books, book sections and conference papers). Annual data sets are provided as individual CSV files in this record.
